混合水压裂工艺实施及效果分析

Implementation and Effect Analysis of Mixed Water Fracturing Process

随着油藏勘探开发的持续稳步推进,渗透率小于0.5毫达西的致密油藏成为油田可持续发展的重要资源保障。本文通过对油藏长C致密储层开展混合水压裂技术试验,得出在相同压力保持水平井中混合水重复压裂效果好于常规重复压裂措施,为实现致密油藏有效开发提供了有力的技术支撑。

As the reservoir exploration and development continue to steadily push forward, the dense reservoir whose permeability is less than 0.3 millidarcy becomes important resources for the sustainable development of oilfield. Mixed water fracturing experiment of Chang C dense reservoir has been carried out. The results show that, under the same pressure, the mixed water repetitive fracturing effect of horizontal wells is better than that of the conventional fracturing measures, which can provide a powerful technical support for effective development of dense oil reservoir.
